[0032] Embodiment:

[0033] As Figures 1 to 4 shown is the positioning and mounting bracket for the aircraft satellite communication antenna of this embodiment, which includes two end support blocks 2, two positioning plates 3, two connecting plates 1, one middle support block 4 and a positioning structure. The positioning structure includes two fixed positioning blocks 5 and one adjustable positioning block 6.

[0034] Two end supports 2 are respectively arranged at both ends of the positioning and mounting frame, and a middle support 4 is arranged in the middle of the positioning and mounting frame. The length of the middle support 4 is greater than that of the end supports 2. Two connecting plates 1 are installed side by side. The connecting plates 1 are perpendicular to both the end supports 2 and the middle support 4, and the end supports 2 and the middle support 4 are connected together through the connecting plates 1. The specific connection structure of this embodiment is as follows: on the upper surfaces of the end supports 2 and the middle support 4, first positioning grooves 10 are provided corresponding to the connecting plates, and on the lower surface of the connecting plate 1, second positioning grooves 1.1 are provided corresponding to the end supports 2 and the middle support 4. The first positioning grooves 10 and the second positioning grooves 1.1 are cooperatively buckled together and fixedly connected through countersunk head bolts 8. The longitudinal positioning of the end supports 2 and the middle support 4 is realized by the connecting plate 1 abutting against the inner side edges of the first positioning grooves 10, and the transverse positioning of the end supports 2 and the middle support 4 is realized by the end supports 2 and the middle support 4 abutting against the inner side edges of the second positioning grooves 1.1.

[0035] Arc surfaces 11 adapted to the curved surfaces of the outer top skin 12 of the aircraft are provided on the bottom surfaces of the end supports 2 and the middle support 4. As Figure 5 shown, during use, the positioning and mounting frame can be attached to the outer top skin 12 of the aircraft through the arc surfaces 11.

[0036] Two positioning plates 3 are respectively fixedly installed on the end supports 2 at both ends. The specific installation structure is as follows: an installation groove 2.1 is provided on the lower surface of the end support 2. One side of the positioning plate 3 is provided with a connecting portion 3.2. The connecting portion 3.2 is embedded in the installation groove 2.1 and fixedly connected through a countersunk head bolt 8.

[0037] End positioning notches 3.1 are respectively provided at both ends of the positioning plate 3. The positions of the end positioning notches 3.1 at both ends respectively correspond to the positions of the lower joints 14.1 of the antenna connectors 14 installed at both ends of the satellite communication antenna. Middle positioning notches 4.1 are respectively provided at both ends of the middle support 4. The positions of the middle positioning notches 4.1 respectively correspond to the positions of the lower joints 14.1 of the antenna connectors 14 installed in the middle of the satellite communication antenna. As Figure 6 shown, during installation, the side edges of the lower joints 14.1 of the antenna connectors 14 are abutted against the inner side edges of the end positioning notches 3.1 and the middle positioning notches 4.1 to realize the positioning of the antenna connectors 14.

[0038] On the positioning plate 3 at one end of this embodiment, there are transverse waist-shaped holes 3.4 and longitudinal waist-shaped holes 3.3. On the positioning plate 3 at the other end, there are transverse waist-shaped holes 3.4. The positions of the transverse waist-shaped holes 3.4 and the longitudinal waist-shaped holes 3.3 can correspond to the original fixed connection holes on the outer top skin 12 of the aircraft. During installation, a positioning pin or fastener passes through the transverse waist-shaped holes 3.4 and the longitudinal waist-shaped holes 3.3 and is connected to the preset fixed connection holes on the outer top skin 12 of the aircraft, thereby achieving fixation. By setting the transverse waist-shaped holes 3.4 and the longitudinal waist-shaped holes 3.3, it can better ensure the position of the positioning mounting frame in the transverse and longitudinal directions.

[0039] Two fixed positioning blocks 5 of this embodiment are fixed on one of the connecting plates 1. An adjustable positioning block 6 is installed on the other connecting plate 1. The specific installation structure of the adjustable positioning block 6 is as follows: The adjustable positioning block 6 is provided with an elongated adjustment hole 6.1. The adjustable positioning block 6 is installed on the connecting plate 1 by passing an adjustment bolt 7 through the adjustment hole 6.1. Loosen the adjustment bolt 7 to adjust the position of the adjustable positioning block 6 within the range restricted by the adjustment hole 6.1. As Figure 7 and Figure 8 shown, the antenna support 13 of the satellite communication antenna itself has a plurality of hollow holes 13.1. The positions of the fixed positioning block 5 and the adjustable positioning block 6 correspond to the hollow holes 13.1 of the antenna support 13 of the satellite communication antenna. During installation, the fixed positioning block 5 and the adjustable positioning block 6 respectively abut against the inner side edges of the hollow holes 13.1 of the antenna support 13, thereby clamping the antenna support 13 of the satellite communication antenna on the positioning mounting frame.

[0040] In this embodiment, receiving grooves 9 are respectively provided on the end support block 2 and the middle support block 4, and the countersunk head bolts for connection are located in the receiving grooves 9, thereby hiding the countersunk head bolts.

[0041] The using process of the positioning mounting frame of this embodiment is as follows:

[0042] Before use, first assemble the positioning mounting frame. First, fixedly connect the two positioning plates 3 to the two end support blocks 2 respectively, and then connect the end support blocks 2 and the middle support block 4 through the two connecting plates 1.

[0043] The specific steps during use are as follows:

[0044] P1. First, it should be noted that: On the aircraft, the outer top skin 12 of the aircraft and the stringers inside for fixing the outer top skin 12 are provided with corresponding fixed connection holes. The outer top skin 12 of the aircraft is fixed on the stringers by passing a fastener through the fixed connection hole and locking it. The fastener can be a fastening bolt or the like.

[0045] When installing the aircraft satellite communication antenna, select the fastener in the middle of the top of the aircraft, remove the corresponding fastener, so as to expose the fixed connection hole for the fastener to pass through on the outer top skin 12 of the aircraft, and use the exposed fixed connection hole as the reference hole.

[0046] P2, position the mounting bracket closely against the corresponding position on the outer top skin 12 of the aircraft. As Figure 5 shown, the arc surfaces 11 of the end support block 2 and the middle support block 4 are in contact with the outer top skin 12 of the aircraft. Moreover, the transverse waist holes 3.4 and the longitudinal waist holes 3.3 provided on the positioning mounting bracket correspond to the reference holes, and then they are connected by positioning pins or fasteners, so that the positioning of the positioning mounting bracket on the outer top skin 12 of the aircraft is first realized, and the problem of difficult reference positioning is solved.

[0047] P3, as Figure 7 and Figure 8 shown, place the antenna bracket 13 on the positioning mounting bracket. The positioning mounting bracket supports the antenna bracket 13 of the satellite communication antenna, and makes the two fixed positioning blocks 5 abut against the inner side edges of the corresponding hollow holes 13.1 on the antenna bracket 13. Then install the adjustable positioning block 6 and make the adjustable positioning block 6 abut against the inner side edges of the corresponding hollow holes 13.1 on the antenna bracket 13. Then lock the adjustable positioning block 6, and clamp the antenna bracket 13 by the fixed positioning block 5 and the adjustable positioning block 6.

[0048] The height of the positioning mounting bracket matches the installation height of the antenna bracket 13. Therefore, after the antenna bracket 13 is clamped on the positioning mounting bracket, the installation height of the antenna bracket 13 is fixed.

[0049] P4, place the lower joint 14.1 of the satellite communication antenna into the end positioning notch 3.1 and the middle positioning notch 4.1 correspondingly. As Figure 6 shown, the side edges of the lower joint 14.1 of the antenna joint 14 are in close contact with the inner side edges of the end positioning notch 3.1 and the middle positioning notch 4.1, realizing the accurate positioning of the lower joint 14.1. The lower joints 14.1 of the six antenna joints 14 are distributed in pairs according to the left, middle and right positions. After the lower joint 14.1 is positioned, fix the lower joint 14.1 on the outer top skin 12 of the aircraft with bolts.

[0050] P5, connect the upper joint 14.3 of the satellite communication antenna with the corresponding lower joint 14.1. As Figure 9 shown, the upper joint 14.3 and the lower joint 14.1 are connected together by a connecting pin 14.2.

[0051] P6, after the upper joint 14.3 is installed, the upper surface of the upper joint 14.3 will fit with the lower surface of the corresponding position of the antenna bracket 13. The upper joint 14.3 itself will be provided with a mounting hole for fixed connection. The original mounting hole on the upper joint 14.3 is used as a reference to drill corresponding mounting holes on the antenna bracket to determine the connection position between the upper joint 14.3 and the antenna bracket 13.

[0052] P7, disassemble the antenna bracket 13 and the upper joint 14.3, then disassemble and take out the fixed positioning mounting frame, and finally reinstall the upper joint 14.3 to the lower joint 14.1 through the connecting pin 14.2, and connect the mounting hole 15 of the antenna bracket to the mounting hole of the upper joint 14.1 accordingly, so as to complete the accurate installation of the aircraft satellite communication antenna and ensure that the positions of the aircraft satellite communication antennas installed on the same model of aircraft are the same.

[0053] The above-mentioned embodiments of the utility model are not intended to limit the protection scope of the utility model, and the implementation methods of the utility model are not limited to these. All other various forms of modifications, replacements or changes made to the above-mentioned structure of the utility model based on the above-mentioned contents of the utility model, in accordance with the common technical knowledge and customary means in the field, without departing from the above-mentioned basic technical ideas of the utility model, should fall within the protection scope of the utility model.
